Biology
The cells of a plant are surrounded by a thick protective layer called the cell wall. Cellulose is a major component of this protective layer. Cellulose is a polysaccharide, a polymer of glucose, (carbohydrate) and it is the most abundant macromolecule on Earth.
- #9. Carbohydrates - Polysaccharides
Molecules contain hundreds/thousands of monosaccharides linked into long chains. Molecules are enormous --> the majority do not dissolve in water --> good for storing energy (starch and glycogen) or for forming strong structures (cellulose)....
- #8. Carbohydrates - Monosaccharides, Disaccharides
Carbohydrates: - Sugar polymers - Molecules contain C, H, O atoms - H atoms are twice as many as C or O atoms (C6H12O6) Monosaccharides The simplest carbohydrates They are sugar: C = 3 = triose C = 4 = tetrose C = 5...
